New description: [New technical field] This creation is about a lamp joint, especially a rotatable LED tube joint. [Prior Art] According to the improvement of living standards, lighting and lighting have gradually received the attention of the public. If appropriate lighting is used in interior and exterior decoration, the lighting not only has practical functions, but also has the function of beautifying the environment. At present, most people still use fluorescent tubes as the light source for lighting. The neon tube is simply a closed gas discharge tube. The main gas in the tube is argon gas and the gas pressure is about 0.3% of the atmosphere. It also contains a few drops of mercury to form a trace of mercury vapor, while the mercury atom accounts for about all. The ratio of one thousandth of the gas atoms, by the current conducted in the tube, forms a gas discharge state and emits light. When the fluorescent tube is applied for a long time, the two ends of the tube will become black, mainly because the electrodes of the fluorescent tube are at both ends of the fluorescent tube, so when the electrodes at both ends are ejected and evaporate, they will adhere to the fluorescent tube. On the side of the tube wall, causing the ends of the tube to turn black. When the two ends of the fluorescent tube gradually become black, it means that the life of the fluorescent tube has gradually come to an end, and the light released by the fluorescent tube is relatively reduced. In addition to the above, the fluorescent tube still has the advantage of a large irradiation area, but the fluorescent tube has the disadvantages of large power consumption and short service life. However, in recent years, the technology of light-emitting diodes (LEDs) has grown and the range of applications has increased, and daily life supplies around our lives have frequently appeared. Light-emitting diodes use high-current-light-emitting 'luminescence The long life of the polar body and the low power consumption, the heat generated by the light-emitting diodes has the above-mentioned environmental advantages, so most of the related companies have begun to develop LE:D lamps. ', although the illuminating-polar body is the illuminant of still brightness, but the volume of the illuminating diode is quite small, so the area relative to the 阙 is limited. If a plurality of lobes are provided, each light diode will still emit light, and the light cannot be concentrated. This is a problem that LED tubes must overcome. The above problems have been solved at present. The main arrangement of the astigmatism is such that the light emitted by each of the light-emitting diodes is dispersed by the astigmatism member. 3 M366638 Although the above problems have been solved today, there are still practical problems in the LED tube, because the direction of the LED tube has a certain directionality, and the illumination range of the fluorescent tube can be three hundred and sixty.
